Application filed May 6,

T 0 all to hem it may concern Be it known that I, EDWARD E. Rose, a citizen of the United States, and aresidentof Swissvale, in the county of Allegheny and State of Pennsylvania, have invented a new and-useful Improvement in Trolley Frogs, of which the following is a specification.

My invention relates to trolley-conductor devices and particularly to approach members for frogs, crossings and similar structures.

One object of my invention is to provide a device of the above indicated character that shall be simple and durable in construction and inexpensive to manufacture.

Another object of my invention is to provide an approach for a trolley-conductordevice that, with its co-operating members, shall comprise a relatively small number of parts and be readily mounted in operative position on a conductor by the use of a simple tool, such as a hammer.

In frogs, crossings, section breaks, splices and any similar device for attachment to a trolley conductor, a renewable approach member, functioning as an arcing tip and wearing guard therefor, is highly desirable to prolong the life of the device and prevent interrupted service. This renewable member should be permitted of mounting and demounting in as short a space of time and with as great facility as it is possible to attain, consequently, nuts, bolts and other devices, that may become locked together by rust, should be avoided.

The handling of small parts, especially where more than one of such parts is used, is very objectionable by reason of the amount of time and labor required thereby. Climatic conditions and the hazards usually attending trolley-line installations make it highly desirable, if not imperative, that workmen employed in such work be given facilities to perform their work with the utmost simplicity of movements.

It is, therefore, my aim to provide a removable approach member, for a frog or other trolley-conductor device, and a composite holding and Wedging member therefor that may be readily moved to and from their operative positions. To this end, I provide a frog or other device having means for the reception of a holding member that may be placed on the frog by a very simple hand movement and an approach member that Specification of Letters Patent.

may be conveniently slipped into operative relation thereto. After this, a few well directed blows of a hammer will serve to se cure the members together.

Figure 1 of the accompanying drawings is a side elevational view of one end of a trolley frog and an approach member embodying my invention; Fig. 2 is a view taken erably of malleable material, projecting from the end 3, has an inverted channel portion 6 for embracing the conductor 2, a plain end face 7 that engages the end 3 and a centrally projecting portion or tongue 8 disposed in the channel 4 above the conductor 2. Oppositely. and outwardly-proj ecting lugs or flanges 9 on the upper edge of the channel. portion 4 at the end 3 support a holding member 10 that is provided with a longitudinal depending wedge portion 11 on its inner surface. End portions 12 of the member 10 embrace the flanges 9 and may be rigidly secured with respect thereto and the portion 11 secured in wedging relation to the tongue 8 by placing the member 10 over the end of the frog and driving the latter home with a few well directed blows of a hammer. The wedge portion 11, in addi tion to a longitudinal slopeatits upper edge, slopes also thereat in transverse directions in conformity with the top of the tongue 8 in order to automatically align the member 10 with respect to the member 4 and the conductor 2 when the approach member 5 is being placed in position.

Reinforcing ribs 13 permit the member 10 to be of substantially minimum weight and maximum strength and effect economy of material therein.

The device is extremely simple and durable in construction, effective in operation, easy to manipulate and, since the wedge portion 11 and the holding member 10 are integral, reduces the number of loose parts to substantially a minimum.

While I have shown and described a particular form of my invention, changes may be efiected therein without departing from the spirit and scope thereof, as set forth in the appended claims.

I claim as my invention:

1. A trolley-conductor device comprising a body member having outwardly-extending oppositely disposed horizontal edge portions, and a wedge member for securing a conductor in position with respect thereto disposed above the body member and having portions extending downwardly around said edge portions.

2. A trolley-conductor device comprising a body member of substantially channel shape for the reception of a conductor, said body member having outwardly-extending transverse portions adjacent to its edges, an approach member having a portion projecting into the end of said channel, and a wedge member engaging all of said portions to hold said members together.

8. A trolley-conductor device comprising a body member of substantially channel shape for the reception of a conductor, said body member having outwardly-extending transverse portions, an approach member having a tongue projecting into the end of said channel and a wedge member formed to co-operatively engage said portions and said tongue to position said members on a conductor. 1

4. A trolley-conductor device comprising a body member of substantially channel shape for the reception of a conductor, said body member having outwardly-extending transverse portions, an approach member ing a portion in said channel, and a member having substantially underhung hook portions embracing said projections and a por- .tion of substantially wedge shape engaging the approach member.

6. A trolley-conductor device comprising a body member, an approach member therefor, and a wedge engaging said members, said approach member and said wedge member having interiitting portions.

71A trolley-conductor device comprising a body member, an approach member therefor and a wedge member for holding said members together, said approach member and said wedge member having a substantially tongue-and'groove connection to each other.

S. A trolley-conductor device comprising a body member, an approach member therefor and a 'longitudinallyslidable wedge member for holding said members together,

said approach member and said holding member having a substantially tongue-andgroove connection to each other.

In testimony whereof, I have hereunto subscribed my name this 23d day of April, 1919.
